We will compare three different technologies for cars. Car A is a conventional gasoline-burning car, which converts about 15% of the fuel energy to power at the wheels. Car B is purely electric and can convert about 65% of electrical energy from the grid to power at the wheels, taking into account losses in the electric motors and in the batteries. The electrical power is supplied by a coal-burning power plant operating at 35% efficiency. ⚫ Car C has a fuel cell that reacts hydrogen fuel with oxygen in air to produce only water as a product. The fuel cell is 50% efficient at converting the energy in the hydrogen to power at the wheels. The hydrogen is produced by steam reforming of natural gas, in which 70% of the energy in natural gas is converted to energy stored as hydrogen, and 100% of the carbon in natural gas is released as CO2. When all three cars are supplying 100 horsepower to the wheels, find the rate of CO2 emission attributable to each car, in grams per second.

Expert Answer:
Answer rating: 100% (QA)
To find the rate of CO2 emission attributable to each car we need to calculate the amount of fuel consumed by each car per second and then calculate the corresponding CO2 emissions based on the carbon ... View the full answer
